Guitar



FIG. 1 is a front view of a guitar showing my new design; and

FIG. 2 is a front view of a guitar, showing an alternate embodiment of FIG. 1.

FIG. 3 is an enlarged front view of the design in FIG. 1, shown separate from the broken line subject matter, for clarity of disclosure; and,

FIG. 4 is an enlarged front view of the design in FIG. 2, shown separate from the broken line in subject matter, for clarity of disclosure.

The broken lines in FIGS. 1 and 2 represent the portions of the guitar, which form no part of the claim. The remaining views of the guitar neck, which are not shown, form no part of the claimed design. 

I claim the ornamental design for a guitar, as shown and described.
